Product details

25 ns trr in a 200 V common-cathode pair — the switching diode for PFC and output rectification

What the 25 ns trr means for the BOM

A 25 ns trr at 6.5 A forward current means the diode recovers before the MOSFET in the same switching leg turns on, reducing the cross-conduction spike. In a 100 kHz PFC stage, that 25 ns window lets the designer use a smaller snubber or omit it entirely, saving two passives per diode. The common-cathode pair in the D2PAK package shares one cathode tab — the board layout ties both anodes to separate switching nodes while the common cathode connects to the output rail, which halves the number of packages compared to two discrete diodes.

Obsolete — no official successor on record

Procurement teams should qualify an alternative for new designs — the 200 V / 6.5 A / 25 ns trr window is common across several ST and competitor fast-recovery dual diodes, but package (D2PAK) and pinout must be verified against the board footprint.

Frequently asked questions

How can I order the STTH1302CG or check current availability?

The STTH1302CG is obsolete with no official successor. We source it through independent distribution — submit an RFQ with your target quantity and we confirm availability and pricing at quote time. No stock-holding claim; sourced per order.

What is the replacement for STTH1302CG?

No official replacement part number is published by STMicroelectronics. For new designs, look for a 200 V, 6.5 A per diode, 25 ns trr, common-cathode dual diode in D2PAK. Several manufacturers offer parts in that parametric window; verify the pinout and PCB footprint against the STTH1302CG before committing.

What are the specs of STTH1302CG?

The STTH1302CG is a dual common-cathode fast recovery diode rated 200 V reverse voltage, 6.5 A average rectified current per diode, with a 25 ns reverse recovery time. Forward voltage is 1.1 V max at 6.5 A. The junction operates up to 175°C. It comes in a D2PAK (TO-263AB) surface-mount package.
